Grammatical problems are a hallmark of DLD, but it has often been noted that children with DLD show variability in their grammatical performance. This study aimed to investigate whether these performance problems are linked to impaired information processing skills. Children and adolescents with DLD (N=60) were compared to age-matched typically developing peers on their comprehension and production of three grammatical aspects that have been shown to be vulnerable in DLD. The production of these aspects was tested in contexts that varied in linguistic complexity. Visual and verbal processing skills were measured and the relation between variability in performance and processing skills was investigated. The results show that grammatical performance in DLD is affected by the linguistic context in which grammatical knowledge has to be implemented, while such effects are small or absent in the TD groups. The effect of context is clearly related to the verbal processing abilities of individuals. Children with poorer verbal processing skills show a larger variability in performance on the grammatical tasks. These results have important implications for theories on DLD and for clinical practice. |
